Council says Valleys landslip site work ‘making good progress’

WORK to restore a Valleys landslip site is on track, and a public consultation will take place to determine the site’s future, Rhondda Cynon Taf Council has confirmed.

The council said in its latest update that it’s making good progress with an initial phase of work to stabilise the slope above the closed path at Tylorstown, and the activity is on course to be completed by the end of October.

Alun Griffiths Ltd was appointed by the council to carry out this additional phase of work, which started on site during the summer.

The work is focusing on the northeast valley mountain side, which is a historical railway cutting lying directly above the remaining closed footpath at the landslip site.

The landslip occurred on the Llanwonno hillside at Tylorstown during Storm Dennis in February 2020.

The landslip, consisting of 60,000 cubic metres of spoil material, blocked the river valley, damaged a sewer, and covered a water main and a footpath/cycle path.

In June, the council’s contractor Walters Ltd completed phases two and three of the agreed remediation plan – which has included embankment scour repairs, moving the spoil material from the valley floor to receptor sites, and the temporary reopening of two of the three shared paths through the site.

The stabilisation work currently ongoing is in addition to phase three.

The landslide led to flows of water creating deep scour lines, damaging revetment walls and depositing debris across the footpath when it rains. Catch ditches were installed to reduce this occurrence last winter.

The work is on course to be completed by the end of the month, as scheduled.
